The invention relates to the drilling of oil and other deep wells and has for its principal object the provision of an improved cover and tool holder of the type shown in my prlor Patent #1,625,774, dated April 19th, 1927.

Afurther object of the invention is the provision of a well casing cover and tool holder that will reduce the expense of manufacture and cost of operation'of devices of this character. Y

A further object of the invention is the provision of a well casing cover and tool holder comprising mating sections, horlzontally arranged, the sections having recesses in their .abutting faces forming the opening in the cover for receiving a tool holding slip, the end walls of said recesses being formed with inwardly extending faces and the slips provided with V-shaped channels in their faces engaging said end walls, said structure providing for holding the sections of the cover in assembled relation and permitting a ready disassembly of the parts when the weight of the tool on the slips has been relieved.

The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawings in which Figure 1 is a view in perspective of the improved cover and showing the slips in position,

Figure 2 is a top plan view of the cover showing the slips in section,

Figures 3 and 4 are sectional details on the planes indicated by the lines 3-3, and 4-4, respectively, of Figure 2.

In the drawings similar reference characters are used to designate corresponding parts throughout the several views.

The cover 1 is designed to be placed on the casing of an oil or other deep well to support a cable, rod, or tube in required position in the well and comprises sections 2 and 3 that are pivotally secured together as shown at 4, the parts 2 and 3 being provided with suitable ears or lugs 5 and 6 to receive the pivot pin 4. The abutting faces of the sections 2 and 3 are formed'with recesses 7 and 8 to receive the slips 9 used for suspending tools by means of a cable in the well, or a drill rod or well 50 tube. The end walls of the recesses 7 and 8 1928. Serial No. 230,791-

shown at 12 in Figure 3, and the rear faces of 13 of the slips 9 are provided with V-shaped channels 14 to engage the inclined faceslO and 11, and hold the sections 2 and 3 in assembled or closed position as illustrated in the drawings. The rear faces 13 ofthe slips 9 are also inclined inwardly and downwardly as shown to conform to the inclined faces 12 of the recesses 7 and 8. The adjacent faces 15 of the slips 9 are provided with longitudinal grooves 16 to receive a cable, rod, tube or the like, and the faces of said grooves may be roughened or'serrated as desired to more effi ciently engage said members.

The free ends of the plates 2 and 3 are provided with ears or lugs 17 and 18, respectively, having alined openings 19 to receive a pin or bolt to hold the members 2 and 3 together in event it should be desired to do so, but it will be apparent that engagement of the V-shaped channels 14 with the inwardly inclined surfaces 10 and 11 when the slips are supporting a cable or rod or the like in the well serve to" efficiently hold the plates assembled. Furthermore, the plates 2 and 3 are reduced at their borders as shown at 20 to reduce the weight of the cover. The upper ends of the. slips 9 are provided with outwardly extending lips 21 that serve to prevent them from slipping the well.

What is claimed is Y A I are inclined inwardlyfrom a horizontal plane A as shown atllOand 11, respectively, and are also inclined inwardly and downwardly as out of the opening in the cover into 1 1. A tool for wells, comprising a casing.

cover formed in separable sections, said sections having complementary recesses in their abutting faces forming an opening in the cover, the end walls of said recesses on opposite sides of the joints between the sections being provided with inwardly extending portions, and slipsengaging'in said opening and straddling the joints between the sections and having faces conforming to said inwardly extending portions to prevent separation of the cover sections.
